Monitoring a resource type in a single CICS system
Stabilized feature: CICSPlex® SM Real-Time Analysis (RTA) is stabilized. Consider moving to Policy system rules or to a dedicated monitoring product such as IBM OMEGAMON for z/OS. See also Stabilization notices and discontinued functions.
In this example, you'll see how to get CICSPlex SM to monitor the LU 6.2 connections in CICS® system CICSPT02, which has recently been experiencing LU 6.2 problems. Both an external message and an event notification are to be issued whenever any connection is found to be in RELEASED status. The monitoring will not be limited to specific hours of the day, but will be continuous.
The task is fundamentally the same as the one shown in the example Monitoring resources permanently. The interesting differences arise
in the creation of the evaluation definition, the action definition,
and the analysis definition. Those steps are shown here:
- Create an evaluation definition.
- From the main menu, click to display the Evaluation definitions tabular view (EVALDEF object).
- Click the Create... button. To base the new definition on an existing one, click the Record check box before clicking the Create... button. The Evaluation definitions create view is displayed.
- Complete the fields as follows:
Name RTEPAY03 Description Connections in CICSPT0 Sample interval 30 Resource name CONNECT Instance identifier of evaluated resource * Method of evaluating results in result set Any Separate task indicator NO Field being evaluated CONNSTATUS Evaluation logical operator EQ Evaluation data value RELEASED Severity assigned when result meets criteria VHS View that may provide extra information CONNECT Filter string TYPE=LU62 - Click Yes to create the definition.
In this example:- The evaluation values define the type of check to be made.
- The Method of evaluating results in result set field value ensures that, if the condition is true of any single connection that's being monitored, the evaluation returns a severity of VHS.
- The filter string limits the checking to LU 6.2 connections.
Note: For a complete description of the Evaluation definitions view, see Filter and modification expressions in evaluation definitions. - Create an action definition:
- From the main menu, click to display the Action definitions tabular view (ACTION object).
- Click the Create... button. The Action definitions create view is displayed.
- Complete the fields as follows:
Name RTAPAY03 Description Connections lost in CICSPT02 Generate event YES Name of view that may provide useful information CONNECT Action priority 255 Message sent when event occurs Connections lost in CICSPT02 Generate external message YES External message sent when event occurs Connections lost in CICSPT02 External message sent when event is cleared CICSPT02 connections now OK Generate generic SNA alert NO MVS automatic restart NO - Click Yes to create the definition.
This action definition tells CICSPlex SM that you want both an event notification and an external message to be issued.
- Create an analysis definition:
- From the main menu, click to display the RTA definitions tabular view (RTA object).
- Click the Create... button. The RTA definitions create view is displayed.
- Complete the fields as follows:
Use the default value of 1 in the Count of true evaluations and Count of false evaluations fields.Name RTDPAY03 Description Connections in CICSPT02 Analysis interval 30 Evaluation expression RTEPAY03 Execute evaluation modification string NO Action definition name RTAPAY03 - Click Yes to create the definition.
CICSPlex SM will evaluate the results of the evaluation definition (defined in RTEPAY03) every 30 seconds.
You would install the analysis definition in the CICS system CICSPT02 by specifying CICSPT02 in the Scope value field of the Install view.
